It's got a difficulty level that harkens back to oldschool sidescrolling shooters. You can change the difficulty, however so it's not quite as impossible. Even then it can be unforgiving. If you're up for a challenge, pick it up. Games like this remind me of the games I played 15-20 years ago & give me a higher respect for the caliber of gamer I was back then. These games today... they've made me soft...
